{Actor} bStatic true, but has Physics set to something other than PHYS_None!: This warning is caused when an actor has its bStatic flag set to true but its Physics is set to PHYS_None. Since bStatic means that the actor will not be moving, having Physics set to PHYS_None is contradictory. Actors set with the bStatic flag are also not ticked(updated). This error can be solved by going to the actor's properties and changing its Physics to PHYS_None.
